Phonemic Inventory. The symbols in Table 1 stand for the distinctive speech
processes that produce the sounds of Aćharêtâʹ. These symbols are used in lieu of customary phonetic
symbols, which are not yet handled by most web browsers.

(The nature of the phonatory and laryngeal processes of Aćharêtâʹ have been determined from
acoustic, visual, and proprioceptive observations of speech. The absence of more sophisticated
observational techniques in the difficult field conditions of the region leaves the precise anatomical
nature of the following tensing processes undetermined.)

Phonation and Laryngeal Accent. The normal unaccented phonation of
vowels in Aćharêtâʹ is produced with a back tensing of the larynx, possibly with a degree of
concomitant posterior voicing.* Throughout the vowel this process produces a fundamental
frequency (F0) that may be more or less progressively lowered, the degree of
lowering corresponding to the intensity of the speech. There is also a slight megaphonic effect. Back
Tensing strengthens slightly over utterance segments, producing a characteristic step-down lowering of
F0 over the length of an utterance (see Fig. 1).

Accented phonation is produced with front tensing, an upward pulling of the
larynx that occurs along with normal back-tensed phonation. This process produces a raised
F0. The range of pitch between accented and unaccented vowels is somewhat narrow,
because of the restriction of larynx raising caused by the concomitant pull of back tensing.

Accented short vowels are indicated by the accent mark (ʹ) preceding the
vowel's symbol. The point during the vowel of highest F0 varies under the influence of
speech intensity and terminal contours.

The position of accent on long vowels is distinctive. On long vowels with beginning accent,
indicated by the accent mark placed before the vowel, front tensing occurs at the beginning of the
vowel and then drops, producing a falling pitch throughout the vowel (see Fig. 2).
On long vowels with ending accent, indicated by the accent mark placed after the vowel, front
tensing occurs at the end of the vowel, while the entire vowel sustains normal back tensing. The result
is a level, falling-rising, or rising pitch across the vowel, depending on the intensity of speech (see Fig. 3). Thus there is a contrast between, e.g., ending-accented râʹt 'night and day [24-hour period]' vs. beginning-accented rʹât 'blood'.

Almost all long vowels with ending accent occur in the final syllable of a word. When such words
take an inflectional suffix, the vowel of the suffix normally receives the accent, in keeping with the
position of the accent at the end of the word; e.g., kâʹl 'year', plural kâlʹa. The two exceptions noted are hâʹt 'hand', plural hʹâta, and jhâʹṭ 'hair', plural jhʹâṭa.

In a few forms ending-accented long vowels appear penultimately. Most of these, like the two
exceptions just noted, contain aspirated voiced consonants which may have influenced their
development: dhrîʹṣṭo 'seen', lhôʹko 'little', mhôʹro 'sweet', ghâʹnu 'big'. The interrogative pronouns
kôʹṛo, kôʹso, etc. 'which one' are compounds of
kôʹ 'who' plus a deictic pronoun. Only ǰâʹbli 'runny
sap' is indeed anomalous; it appears to be based on a Pashto loanword.

Accented phonation may occur on the penultimate or the final syllable in a word. Antepenultimate
accent apparently occurs only when suffixes are added to a word; e.g., šʹâlak
'locust', plural šʹâlaka, mhʹâruc̣i mʹuṭ 'mulberry
tree', cf. mhârʹôc̣o 'mulberry'.

A few words contain an accented vowel immediately following an unaccented vowel: dhiʹûṛo 'daughter's son', lôbiʹa 'string bean', etc. In cases
where a long vowel precedes another vowel, the accent mark indicates beginning accent on the following
vowel, rather than an ending accent on the preceding vowel: kôṭaghâʹûčo
'male from kôṭaghâʹ', etc.

Secondary Accent. The presence of a secondary accent appears confirmed by full
waveform plots of speech, which show a greater amplitude or duration for vowels that are subjectively of
secondary prominence. Such vowels do not show the raised F0 of laryngeal
front-tensing; they are probably produced by increased glottal opening.

Vocalism. The articulatory processes of mandibular opening, lingual
fronting, and labial rounding produce the five contrasting vocalic qualities of Aćharêtâʹ
(see Table 1). To these may be added the process of lengthening ( ^ over a vowel's symbol), which produces a contrast between long and short
(unmarked) vowels; e.g.,

ṣʹîng 'Shîng' [ethnonym] vs. ṣʹing
'horn',

kʹûṭ 'tower' vs. kʹuḍ 'wall',

ḍʹâg 'male markhor' vs. ḍʹang 'hard',

trʹô 'three' vs. trʹoko 'thin',

bʹêǰi 'heifer' vs. bʹe 'we'.

Laryngeal Effect on Vocalism. There is a degree of linkage between the tensing of
the larynx and the position of the base of the tongue: normal laryngeal back-tensing tends to pull the
tongue back and down, while laryngeal front-tensing pushes the base of the tongue up. Back-tensing
restricts the fronting of the short vowels e and i
and the opening of a, while accentual front-tensing has engendered vocalic
changes at times during the evolution of Aćharêtâʹ.

Vocalic Processes within the Word. Both laryngeal accent and the anticipation of the
fronting of a following i ("umlaut") have at different times determined the
vocalic makeup of modern words in Aćharêtâʹ. The vowels in such words contrast with those in
morphologically related forms that have not been affected by these processes, giving rise to vocalic
alternations such as:

The determining processes of accent and anticipation apparently spawned processes of vocalic change
in the following stages:1

1. beginning accent was strengthened, pushing the tongue up and closing a long open
ʹê or ʹô, so that ʹê
became ʹî and ʹô became ʹû;

2. a following i was anticipated on a preceding â, fronting the â to ê;

3. beginning accent was strengthened on long open ʹâ by
rounding, so that ʹâ became ʹô;

4. accent lengthened a short vowel, so that ʹa became ʹâ, etc.

5. deaccenting shortened a long vowel, so that ʹâ became
a, etc.

There are exceptions to each process; none is automatic in the current language. Chronological details
of these processes of change are still being sorted out to best account for the exceptional cases. The
processes are discussed below.

Closing. Open, beginning-accented long vowels became closed under the
tongue-raising effect of laryngeal front-tensing, while corresponding ending-accented or unaccented long
vowels remained open; e.g.:

Such anticipation apparently did not occur if the preceding vowel was originally short:

*tʹapya- 'be hot' became later tapʹiǰ- 'get
heated'.

Other exceptions include ǰʹâmi 'mandible' and ac̣hʹâṛi 'walnut tree'.

Rounding. In addition to the direct effect of laryngeal tensing on vowels, there was a
sympathetic process of lip-rounding on beginning-accented long ʹâ, which
became ʹô. Ending-accented or unaccented â
remained; e.g.:

Most instances of ʹô in the current language arose from this process in earlier
times.

Vocalic Tensing ("Lengthening"). During vocalic tensing the articulatory processes are strengthened, producing increased opening or fronting and lengthening the vowel. Accented short vowels doubled in length as the tongue was pushed farther up and out, while unaccented or sequential short vowels remained short, as seen in the alternations of vowels in inflected forms:

ac̣hʹî 'eye' vs. ac̣hʹia 'eyes',

gʹû 'bull' vs. gʹua 'bulls'.

nʹû 'nine' vs. nuwʹim 'nine [ergative]'

dhîʹ 'daughter' vs. dhiʹa 'daughters'

khâʹr 'donkey' vs. kharʹa 'donkeys'

ghôʹṣṭ 'house' vs. ghoṣṭʹa 'houses'

Within such forms the same total vocalic strength, as measured in moras, is maintained in both inflected
and uninflected words, the length of a tense vowel being equivalent to that of two short vowels.

However, there are many morphologically related forms that show no such alternations, having
derived from earlier forms with tense vowels:

šîʹš 'breath' and šîšʹi 'breaths',

sûʹd 'profit' and sûdʹi 'profits',

čhâʹl 'kid' and čhâlʹa 'kids',

čôʹr 'thief' and čôrʹa 'thieves',

ḍhêʹr 'belly' and ḍhêrʹi 'bellies'.

Sequences of Vowels.

gôkhʹî 'Chitrali' vs. gôkhʹia 'Chitralis',

bêṭʹi 'lamb' vs. bêṭiʹa 'lambs',

lôbiʹa 'string bean' vs. lôbiaʹi 'string beans',

lâṛʹu 'squash' vs. lâṛuʹa 'squashes',

gʹû 'bull' vs. gʹua 'bulls',

nʹô 'name' vs. nʹôwa 'names',

rhôʹ 'song' vs. rhôwʹa 'songs',

bhrʹo 'brother' vs. bhrâwʹu 'brothers',

phôʹ 'boy' vs. phayʹa 'boys',

ghâʹw 'cow' vs. ghêʹi 'cows',

pitriǰâlôʹ 'cousin' vs. pitriǰâlêʹ 'cousins',

čôlâʹ 'language' vs. čôlaʹi 'languages',

haḍmêʹ 'marrow' vs. haḍmêʹi 'marrow [loc.]',

Nasalization.

Consonantism.

Voicing. Consonants may be voiced (Figures 5 and 7) or voiceless (Figures 8 and 9).
Voiced consonants have the default back-tensed voicing, slightly strengthened to compensate for the
back pressure generated by the oral stricture, as indicated by a characteristic drop in F0
across the consonant. Unaspirated y appears to lack this drop, indicating
that it may be produced with front tensing; see Fig. 5. Voiceless consonants are
produced with an interruption of the airflow through the glottis, by an unclear process. The
F0 component of vowels following voiceless consonants is unperturbed, indicating that
laryngeal back tensing is relaxed (or possibly the larynx is slightly front-tensed) during voiceless
consonants. Distinctive voiced–voiceless contrasts appear among the obstruents, with voicelessness as
the accentual ("marked") component; sonorants are by nature voiced. Voiced and voiceless consonants
may appear in initial, medial, or final position.

Aspiration. Aspiration is a turbulent flow of air through the glottis. Aspiration may stand
alone as a consonantal sound (represented by h) or as an accentual
component of a consonant, forming an aspirated consonant (represented by h following the symbol for the consonant). The turbulence peaks
after the release of the oral stricture, more so for continuants than for stops (see the waveforms
in Figures 4, 6, and 8). Aspirated
consonants contrast with plain (unaspirated) consonants (Figures 5, 7, and 9), which are released directly into a following sound
without intervening turbulence. Aspirated consonants do not occur in final position.

The location of aspirational turbulence in the glottis is determined by the voicing component of the
consonant: in voiced consonants the location is posterior glottal; in voiceless consonants
the location is (apparently) full-glottal.

In aspirated voiced consonants the posterior glottal stricture is produced in concert with the normal
laryngeal back tensing of phonation. The result is a posterior whispery voiced* sound. Whispery voice occurs alone as
non-initial h, as a component of an aspirated voiced stop, e.g.,

ghôʹm 'wheat' (cf. gôʹ
'where'),

J̣haṇJ̣ʹîr 'chain',

ǰhʹip 'tongue' (cf. ǰêʹb
'pocket'),

dhîʹ 'daughter' (cf. dʹî 'from'),

ḍhôʹr 'hopper' (cf. ḍʹôk
'back'),

bhʹîro 'male goat' (cf. bʹîḍo
'much'),

or as a component of an aspirated voiced continuant, e.g.,

yhʹûm 'I will come' (cf. yʹû 'barley'),

lhôʹṇ 'salt' (cf. lôʹ 'cedar'),

rhôʹ 'song' (cf. rʹôt 'night'),

zhâʹy 'place' (cf. zʹaṛ
'poison'),

mhârʹânu 'killing' (cf. mârʹânu
'dying'),

whʹî 'he will come down' (cf. wʹî
'water').

No aspiration has been recorded with the continuants n and ṇ, nor with ṛ or the rare, borrowed sounds ẓ and ǧ.

After a voiceless consonant the accentual turbulence appears as full-glottal voiceless breathy
phonation.* The heightened air
flow of the full-glottal opening is barely contained by the labial closure of the aspirated stop ph, which releases with a spirantal off-glide or merges with bilabial f. Examples of aspirated voiceless consonants include:

khâʹl 'threshing floor' (cf. kâʹl 'year')

c̣hʹôṇ 'hollyoak' (cf. c̣o˜ṭ-
'write')

čhʹay 'shade' (cf. čʹay 'tea')

ṭhʹongi 'ax', (cf. ṭʹombo
'trunk')

thʹî 'thy' (cf. tʹî 'he [ergative]')

phalʹûṛo 'grain' (cf. palʹûlo 'male
Aćharêtâ' speaker')

baćhâʹr 'young ox' (cf. kućʹa 'trap
door')

The turbulence of an initial h starts out voiceless and becomes whispery
voiced by its end. The delayed appearance of whispery voice indicates a latency in that process.

Within a simple, noncompounded word only one point of aspiration occurs, almost always at the
beginning of the word. Non-initial aspiration may occur alone (lohʹoylo 'red',
rohʹiṇ 'urial') and with affricates (ac̣hʹî 'eye',
gućhʹî 'morel'), and it occurs in small group of forms that show etymological
pecularities; e.g., forms with ancient prefixes (âghâʹ 'sky', oḍhʹôl 'flood'), loanwords (sithâʹr 'sitar'), and a few other
words (buṭhʹe 'all', baḍhʹîr 'sledgehammer',
gôkhʹî 'Chitrali', etc.).

Transition. The system of transcription used here indicates word boundaries for
clarity. Sounds within a word are produced in close transition, which may imply the overlapping
(coarticulation) of certain articulatory components of adjacent sounds. Across a word boundary
(indicated by a space) sounds are produced with lexical transition, in which fewer types of
components overlap. However, the sounds across some word boundaries may be produced in close
transition, in which case the words are linked together by an underline (_)
rather than separated by a space. The normal overlap of lexical transition may be broken, as
indicated by a comma (,).

The types of transition are summarized in Table 2.

Notes

1. Stage 1 must precede Stage 2, otherwise the ʹê from
Stage 2 would be closed during Stage 1, giving *nʹîṛi 'creek'. Likewise, Stage
1 must precede Stage 3, otherwise the ʹô from Stage 3 would be closed
during Stage 1, giving *dʹûdo 'father's father'. Stage 2 probably preceded
Stage 3, otherwise both â and ʹô (from Stage 3)
would have to be fronted during Stage 2. Stage 4 must follow the other stages, otherwise accented short
vowels would have been lengthened and subjected to the processes of Stages 1–3. It appears that if the
position of the accent changed after determining this cascade of processes, the cascade occurred again,
so that *uḍhâwʹi 'having fled' > uḍhêwʹi 'having
fled' > *uḍhʹêwum 'I'll flee' > uḍhʹîum 'I'll flee'.
